If you're looking for an eco-friendly way to keep your cooled beverage cold for hours on end, then a vacuum-insulated water bottle is the perfect option for you! In this article, we'll take a closer look at what makes these bottles so efficient and beneficial, and explain why it's important to get one if you drink a lot of cold drinks!
A vacuum insulated water container, also known as a 'vaco,' is a reusable drink container that uses vacuum insulation to keep your beverages cold or hot for up to 24 hours. The technology was first developed in the 1920s and has been growing in popularity recently because of its environmental benefits.
A vaco typically consists of a stainless steel or plastic bottle with an attached insulated sleeve. When you want to drink from the bottle, you simply unscrew the top and empty its contents into your mouth. To keep drinks cold or hot, the manufacturer places either a chunk of ice or an airtight thermal pouch inside the sleeve.
When you're done with the bottle, just screw it back on and deposit it in your recycling bin. There are two main types of vacuum insulation used in water bottles: thermal and hydrostatic. Thermal insulation uses a layer of foam to absorb energy from heat waves before they can damage metal parts inside the vaco.
Hydrostatic insulation uses a pressure differential between two fluids to prevent heat from escaping from the vaco. The modern vacuum-insulated water bottle is a marvel of technology. It works by using a vacuum to create a sealed environment around the water bottle that helps keep the water cold for hours or even days.
